In various embodiments and with reference to FIGS. 1 and 2A-2B, multi-barrel revolver 100 may comprise a frame 110, a cylinder 120, and a firing mechanism 130. Frame 110 may be configured with and/or comprise a handle 112, a trigger guard 114, and a flash hider 116. Frame 110 may also be configured with any suitable groove and/or sight system including, for example, sight system 118. Sight system 118 may comprise a front sight and/or a rear sight. Cylinder barrel 120 may rotatably couple to and/or install on frame 110. Cylinder barrel 120 may comprise one or more barrels (e.g., six barrels including, for example, barrel 122A, barrel 122B, barrel 122C, barrel 122D, barrel 122E, and barrel 122F, as shown in FIGS. 1 and 2A).

In various embodiments, cylinder barrel 120 may rotate about a shaft 124. In this regard, cylinder barrel 120 may comprise and/or define a central channel. Shaft 124 may be receivable in the central channel of cylinder barrel 120. Cylinder barrel 120 may be rotatably coupled to frame 110 by any suitable support including, for example, support 126. More specifically, support 126 may operatively couple and/or rotatably couple to shaft 124. In this regard, support 126 may couple and/or attach cylinder barrel 120 to frame 110 via shaft 124.

In various embodiments, cylinder barrel 120 may actuate from a loading position to a firing position. In the loading position (e.g., when cylinder barrel 120 is rotated out of frame 110), an operator may have access to the various chamber/barrels of cylinder barrel 120 (e.g., barrel 122A, barrel 122B, barrel 122C, barrel 122D, barrel 122E, and barrel 122F, as shown in FIGS. 1 and 2A). In the firing position (e.g., when cylinder barrel 120 is rotated with frame 110), revolver 100 may be fired (e.g., discharge a bullet from one or more barrels, including, for example, barrel 122A, barrel 122B, barrel 122C, barrel 122D, barrel 122E, and barrel 122F, as shown in FIGS. 1 and 2A) in response to firing mechanism 130 being activated (e.g., a trigger 134 being pulled).

In various embodiments and with reference to FIGS. 2A and 2B, firing mechanism 130 may comprise a trigger 134, a hammer 136, and a firing pin 132. Firing mechanism 130 may be installable in frame 110. More specifically, trigger 134 may install through frame 110 and be surrounded by trigger guard 114. Hammer 136 may rotatably install in and/or movably attach to frame 110. Hammer 136 may also be operatively coupled to trigger 132. Housing 110 may further define a firing pin channel.

In various embodiments, firing pin 132 may be installed in the firing pin channel of housing 110. In this regard, hammer 136 may be actuated by a user and by depressing trigger 132, causing hammer 136 to strike firing pin 132. In operation and in response to firing pin 132 being struck by hammer 136, a primer or rim of a bullet may be ignited causing the bullet to be activated.

In various embodiments, the ignition point of various calibers of ammunition may vary. As such, cylinder barrel 120 and firing pin 132 may be designed to insure that firing pin 132 aligns with at least a portion of the activation surface for each of the various calibers. In this regard, firing mechanism 130 may employ a floating firing pin architecture. The architecture may provide a system that is capable of activating and/or igniting any suitable caliber of ammunition that may be found and/or available.

In various embodiments, floating firing pin mechanism 130 may be configured with a cylinder barrel 120 that comprises a plurality of chambers that are suitably dimensioned within the chamber such that firing pin 132 strikes a round of ammunition at an activation point (e.g., a rim and/or a primer). In this regard, firing pin 132 may be configured to strike a primer of a round of ammunition and/or a rim of a round of ammunition and/or any other suitable activation point. By employing floating firing pin mechanism 132 in a revolver (where a typical revolver may rely on a hammer striking the activation point of ammunition), revolver 100 may provide an operator with a system and/or revolver apparatus that is capable of firing any suitable ammunition that is available and/or can be secured through scavenging.

In various embodiments, the various chamber location of cylinder barrel 120 may be located such that the activation points of various calibers of ammunition (e.g., the primer and/or rim of a round of ammunition) are aligned with the floating firing pin mechanism 132. In this regard, the various activation points of multiple calibers of ammunition of a loadable into a single cylinder barrel may share a common activation point along a circumference of cylinder barrel 120.

In various embodiments and in operation, hammer 136 may be actuated by a user to set the position of trigger 132 in a single action operating mode. Trigger 132 may also be depressed and/or actuated by a user causing hammer 136 to cycle and strike firing pin 132 (in a double action operating condition). In this regard the actuation of either trigger 132 and/or hammer 136 may cause cylinder barrel 120 to rotate. This rotation aligns a bullet and/or chamber with firing pin 132 allowing for activation of the bullet and/or ammunition.

In various embodiments and with reference to FIGS. 2A-2B, and FIG. 3, cylinder barrel 120 may rotatably and removably couple to frame 110. In this regard, support member 126 may be configured to receive and/or support cylinder barrel 120 and shaft 124. Shaft 124 may be installable through cylinder barrel 120, a spring 123 and a guide 121. Shaft 124 may further couple to an attachment shaft 127 and ejector 129. Shaft 124 may be movable within cylinder barrel 120 causing ejector 129 to move, linearly, relative to the longitudinal centerline of cylinder barrel 120. When ammunition is loaded into cylinder barrel 120 ejector 129 may operatively engage the cases of various calibers of ammunition in order to clear one or more chamber/barrels (e.g., barrel 122A, barrel 122B, barrel 122C, barrel 122D, barrel 122E, and barrel 122F, as shown in FIGS. 1 and 2A) in response to one or more rounds of ammunition (e.g., of the same caliber or various calibers) being fired.

In various embodiments and with reference to FIGS. 4A-4J, cylinder barrel 420 may be chambered and rifled with one or more calibers. Moreover, cylinder barrel 420 may be chambered and/or rifled with any suitable caliber to fire any suitable caliber of ammunition. For example, cylinder barrel 420 may be chambered is a single caliber (e.g., as shown in FIGS. 4A-4H), in two calibers (e.g., as shown in FIG. 4J), in three calibers, and/or in multiple calibers (e.g., as shown in FIG. 41). In various embodiments, a single chamber (e.g., a chamber sized for 0.357 may be capable of receiving, firing and delivering various calibers including for example 38 special and/or a chamber sized for 410 shotgun may be capable of receiving, firing and delivering 45 long Colt (i.e., LC)).

In various embodiments, cylinder barrel 120/420 may be reconfigurable. In this regard, the various chamber/barrels (e.g., barrel 122A, barrel 122B, barrel 122C, barrel 122D, barrel 122E, and barrel 122F, as shown in FIGS. 1 and 2A) of cylinder barrel 120/420 may be removable and/or sleevable. In this regard, a single cylinder barrel may be capable of being configured by a user to shoot any combination of rounds of ammunition in any caliber.

In various embodiments, the multi-barrel/multi-caliber revolvers and system disclosed herein may be capable of providing an operator with an efficient firearm system. The firearm system may be customizable, reconfigurable and/or capable of shooting any suitable caliber of ammunition.
